Abstract

Present work describes the inverse problem for identification of material and support type properties of flexible dolphin structure. Most liquid bulk terminals are equipped with a jetty as berthing facility. The ship mostly berths to dedicated breasting dolphin structures, which can be single-pile flexible/rigid dolphins or multi-pile flexible/rigid dolphins. This work considers dolphin motion as massspring damped system where cantilever approximation mimics dolphin pile. Few measurements have been made for the dolphin structure, which is approximately 30 m long, 15 m immersed in the bottom and placed about 2-3 m above the sea level. The elastic material properties and pile support were identified via inverse method combined with displacement measurements of dolphin head.

柔性海豚结构材料和支撑性能的实验估算
目前的工作描述了识别柔性海豚结构材料和支撑类型特性的反问题。大多数液体散装码头都配有码头作为停泊设施。该船主要停泊在专用的靠船墩结构上,可以是单桩柔性/刚性靠船墩,也可以是多桩柔性/刚度靠船墩。本文将海豚运动视为质量弹簧阻尼系统,悬臂近似模拟海豚桩。对海豚式结构进行的测量很少,该结构长约30米,沉入海底15米,位于海平面以上约2-3米处。通过反求法结合海豚头位移测量,确定了弹性材料特性和桩支撑。
